Mathias Nyman 7faac1953e xhci: avoid race between disable slot command and host runtime suspend ... Make xhci_disable_slot() synchronous, thus ensuring it, and xhci_free_dev() calling it return after xHC controller completes the disable slot command. Otherwise the roothub and xHC host may runtime suspend, and clear the command ring while the disable slot command is being processed. This causes a command completion mismatch as the completion event can't be mapped to the correct command. Command ring gets out of sync and commands time out. Driver finally assumes host is unresponsive and bails out. usb 2-4: USB disconnect, device number 10 xhci_hcd 0000:00:0d.0: ERROR mismatched command completion event ... xhci_hcd 0000:00:0d.0: xHCI host controller not responding, assume dead xhci_hcd 0000:00:0d.0: HC died; cleaning up Cc: <stable@vger.kernel.org> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20211210141735.1384209-3-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2021-12-10 15:34:01 +01:00
